The above procedure may, in turn, be followed by modification of the lactam formed, should a different lactam starting material be desired. For example, a cis-1-p-methoxyphenyl-3-acetoxy-4-phenylazetidin-2-one racemate prepared as above, in acetonitrile at a temperature such as -10° C. to -5° C., may be treated with a solution of ceric ammonium nitrate in water to yield a cis-3-acetoxy-4-phenylazetidin-2-one racemate. The latter compound may, for example, further be hydrolyzed, e.g., with aqueous potassium hydroxide, to yield cis-3-hydroxy-4-phenylazetidin-2-one.
